NAME

       XkbAddGeomRow - Add a row to a section

SYNOPSIS

       XkbRowPtr XkbAddGeomRow (XkbSectionPtr section, int sz_keys);

ARGUMENTS

       - section
              section to be updated

       - sz_keys
              number of keys to be reserved

DESCRIPTION

       Xkb  provides functions to add a single new element to the top-level keyboard geometry. In
       each case the num_ * fields of the corresponding structure  is  incremented  by  1.  These
       functions  do  not  change  sz_*  unless there is no more room in the array. Some of these
       functions fill in the values of the element's structure  from  the  arguments.  For  other
       functions, you must explicitly write code to fill the structure's elements.

       The  top-level  geometry  description  includes a list of geometry properties.  A geometry
       property associates an arbitrary string with an  equally  arbitrary  name.  Programs  that
       display  images  of  keyboards  can  use  geometry  properties  as hints, but they are not
       interpreted by Xkb. No other geometry structures refer to geometry properties.

       One of the components of a keyboard  geometry  section  is  one  or  more  rows  of  keys.
       XkbAddGeomRow adds one row to the specified section.  The newly created row contains space
       for the number of keys specified in sz_keys.  They are allocated and zeroed, but otherwise
       uninitialized.   XkbAddGeomRow returns NULL if any of the parameters is empty or if it was
       not able to allocate space for the row. To allocate space for an arbitrary number of  rows
       to a section, use the XkbAllocGeomRows function.
